Puerto Rico is a Caribbean island and unincorporated U.S. territory with a landscape of mountains, waterfalls and the El Yunque tropical rainforest. In San Juan, the capital and largest city, the Isla Verde area is known for its hotel strip, beach bars and casinos. Its Old San Juan neighborhood features colorful Spanish colonial buildings and El Morro and La Fortaleza, massive, centuries-old fortresses.

Puerto Rico is beloved by travelers around the world, and for good reason.

From bioluminescent bays, pristine Caribbean beaches and lush forests to historic streetscapes, a vibrant local food scene and fascinating cultural attractions, each region of Puerto Rico offers visitors a distinct experience.

And there's simply never a bad time to visit. Better yet, you can often find cheap nonstop flights to both San Juan's Luis Muñoz Marín International Airport (SJU) and Aguadilla's Rafael Hernández Airport (BQN) on the stunning northwest coast. If you're traveling from the U.S., you don't even need a passport or have to change your money.

It's a perfect tropical weekend getaway from the Eastern Seaboard; you can board an early morning flight and enjoy lunch and a pina colada with your toes in the sand.
